Book Description
Excerpt from A Memoir on the Palaeozoic Reticulate Sponges Constituting the Family Dictyospongidae Species, a paper prepared at my request by Mr. John M. Clarke. \vith this publication, forty-two species of these sponges had been described from the palaeozoic rocks of the United States. So rapid has been the growth of these collections and so generous the disposition of all collectors and students toward the perfecting of this monograph, that to-day we present descriptions of about thrice the number of specific forms recognized as such, seven years ago. This wonderful increase is not especially a matter for congratulation, save that it serves to show the amazing diversity of these siliceous sponges in late Devonian and early Carboniferous faunas. The species and genera are established in accordance with the best standards attainable for these variable organisms. Future collections and observations may show that these divisions are not in all cases sharply defined they will undoubtedly Show that the present account of this organic element in these ancient rocks is far from being complete. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at www.forgottenbooks.com This book is a reproduction of an important historical work. Forgotten Books uses state-of-the-art technology to digitally reconstruct the work, preserving the original format whilst repairing imperfections present in the aged copy.
